OIL CAN.

Application tiled March 16, 1928. lSerial No. 95,054.

The invention relatesto oil cans,jan d has for its object tov provide a device of this character which will be free from clogging at all times, and one wherein a piston is fed downwardly from time to time for insuring a forced feed of the oil from the can, consequently preventing clogging of the discharge spout.

A further object is to provide within the chamber of the can vertically disposed parallel guide rods on which the piston is slidably mounted and a rotatable threaded discharge tube extending downwardly into the chamber and threaded through the piston, and by rotation of which the piston may be fed downwardly as the oil is consumed, and which piston when it engages the bottom of the can will prevent rotation of the threaded discharge tube and will indicate the can is empty. j

A further object is to provide the can with a removable bot-tom thereby allowing the can to be filled from the bottom.v Also to provide a handle member clamped on the upper end of the discharge tube and adapted to be grasped by the operator for rotating the tube. A further object is to provide the piston with packing engaging the wall of the can which will prevent leakage of oil past the piston during a force feed operation.

llith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made vwithin the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawing the single ligure shows a vertical transverse section view through the oil can, and in which figure the numeral l designates the receptacle of the cap, in the chamber 2 of which oil is placed after removing the removable bottom 3, which is threaded at 4 on the lower end of the receptacle 1. Disposed on thc upper side 5 of the receptacle 1 is a reinforcing plate 6, and extending through said reinforcing plate is a threaded end 7 of downwardly extending guide rods which guide rods are in parallel relation to each other, and to the threaded discharge tube 9. The rods aresecured to the top 5 by means of nuts disposed on opposite sides of the top 5, and engaging washers 11, which washers not only brace the top butform an airtight joint which will prevent seepage of oil through the top 5. Slidably mounted within the chamber 2 and engaging the wall of the receptacle is a piston 12, which piston comprises a. disc 13, which engages the upper side of a felt sheet 14, a flanged washer and a bottom dished plate 16 which engages the under side of the washer" 15, all of which parts are held together in close engagement by means of bolts 17. The guide rods 8 extend through the piston 12, and it is obvious when the discharge tube 9 which is provided with left hand threads and threaded through the piston 12 is rotated, the piston 12 will be fed downwardly or upwardly according to the direction of rotation of the tube. lVhen the piston is fed downwardly, oil within the chamber 2 below F .the piston is forced upwardly through the tube 9, however it is the design of the `deviceto exclude all air in the chamber 2 below the piston l2 so that the can may be used by flexing the spring bottom 18 thereof in f the usual manner. ,i

Tube 9 is rotatably mounted in a bearing 19 in the top 5 and the plate 6 and has clamped thereon by means of a bolt 20 above the washer 21 a handle member 22 adapted to be grasped by the operator for rotating' the threaded tube 9. Threaded tube 9 is provided with a nut 23 which engages a washer 24, which in turn engages the under side of the top 5 of the receptacle, consequently an oil tight joint is provided, and one which will allow rotation of the threaded tube 9. Threaded at 25 on the upper end of the tube 9 is a discharge spout 26, which is of a conventional structure, and which may be easily and quickly removed as desired.

F rom the above it will be seen that a force feed oil can is provided, in which a rotatable threaded tube is mounted, which when rotated will positively7 feed upwardly or downwardly a piston within the can, thereby forcing oil through the tube to the discharge spout, and which will positivelyprevent permanent clogging of the discharge spout, and will insure a free discharge of oil at all times. It will also be seen'that the device is simple in construction, posi* tive in its operation and one which may be cheaply manufactured and sold.

The invention having been set' forth what is claimed as new and useful is An oil can comprising a casing having an ics i oil chamber therein, a piston slidably niountthrough said top and reinforcing plate, nuts ed Within the oil chamber of the casing, a carried by the guide rods and cooperating threaded discharge tube rotatably mounted with the top and plate for anchoring the in the casing and extending into the oil guide rods, ahandle member clamped on 15 5 chamber and threaded through the piston, the upper end of the discharge tube, a Washspaced parallel guide rods carried by the er interposed between the handle member casing and in parallel relation to the threadand the reinforcing plate, and a nut carried ed discharge tube and on which the piston is by" the discharge `tube and engaging theinslidably mounted, a top carried by said casner side of the top. 20
